Catalytic chain-breaking pyridinol antioxidants

10.1021/jo902226t

The study focuses on the synthesis and evaluation of 3-pyridinols, which are compounds carrying alkyltelluro, alkylseleno, and alkylthio groups, as potent antioxidant agents. These pyridinols were tested for their ability to inhibit azo-initiated peroxidation of linoleic acid in a water/chlorobenzene two-phase system and in a homogeneous phase. The chemicals used in the study include various 3-pyridinols with different substituents, N-acetylcysteine (NAC) as a water-soluble co-antioxidant, and N-tert-butoxycarbonyl cysteine methyl ester (LipCys), a lipid-soluble analogue of NAC. The purpose of these chemicals was to assess their antioxidant activity, specifically their capacity to quench peroxyl radicals, regenerate through reduction by thiol reducing agents, and their potential catalytic antioxidant behavior. The study aimed to understand the kinetic, thermodynamic, and mechanistic aspects of these antioxidants' activities and to identify the structural features that contribute to their high reactivity and effectiveness.
